The book is based on the notes from the graduate course given by the author at Rutgers University in the fall of 1994 and the spring of 1995. The main goal of the book is to acquaint the reader with various perspectives of the theory of automorphic forms. In addition to detailed and often nonstandard exposition of familiar topics of the theory, particular attention is paid to such subjects as theta-functions and representations by quadratic forms.
A very nice introduction to the theory of automorphic forms with a very clear treatment to the wide range of topics. A very nice treatment of the theory on gamma_0(N) as well. Poincare series are treated in detail and in a very nice fashion. I highly recommend this book for those who want to learn the analytic treatment of modular forms. Thumbs up.
